What are the round hole perforation designs
Round hole plastic perforated sheet is very popular in both industrial and chemical industries. Plastic sheet with round holes are widely used for filtering sheets,protective panels,dipping components and decorative panels etc. For example, polypropylene plastic perforated sheets with 1mm holes can be cut into filtering discs,high density polyethylene sheet with 3mm to 5mm holes can be used to make dipping baskets for industrial areas in acid liquids. Perforated PP and HDPE sheeting can also be used for sterilization layer pads.
There are usually three kinds of round hole perforation design,namely staggered rows perforation including 60 degree staggered pitch and 45 degree staggered pitch, straight rows perforation.
When we design the round hole perforation, we must take the thickness of the plastic sheet,the hole diameter and the hole center distance into consideration, generally speaking, the hole diameter should be equal to or more then the thickness of the plastic sheet.
